According to the fire extinguishing system according to claim 1, since at least a part of the housing means for the fire extinguishing device is composed of only a frame frame surrounding the fire extinguishing device, for example, the fire is extinguished through an opening between the frames. Since the fire extinguishing device inside the fire extinguishing device accommodating means can be easily accessed from the outside of the device accommodating means, workability such as maintenance of the fire extinguishing device can be improved. Further, for example, since the fire extinguishing device inside the fire extinguishing device accommodating means can be directly visually observed from the outside of the fire extinguishing device accommodating means through the above-mentioned opening, the failure location of the fire extinguishing device (for example, damage to the appearance, etc.) Can be easily identified. Further, for example, since it is not necessary to provide a material (for example, sheet metal or the like) surrounding the fire extinguishing device on the entire surface of the accommodating means for the fire extinguishing device, the material cost for manufacturing the accommodating means for the fire extinguishing device can be reduced. .. Further, for example, since it is not necessary to provide a material (for example, sheet metal, etc.) surrounding the fire extinguishing device on the entire surface of the accommodating means for the fire extinguishing device, the weight of the fire extinguishing system can be reduced, and the portability of the fire extinguishing system can be improved. Installability can be improved. Further, for example, since the fire extinguishing device housed in the fire extinguishing device accommodating means can be held, the fire extinguishing device can be fixed at a predetermined position.

According to the fire extinguishing system according to claim 2, by providing the mounting means, for example, the electric equipment related to the fire extinguishing device can be attached, so that the electric equipment can be used for the fire extinguishing device or together with the fire extinguishing device. (For example, any electric device including a telephone used for maintenance) can be used. Further, for example, since it is not necessary to provide the electric equipment for the predetermined electric device separately from the fire extinguishing system, the space of the place where the fire extinguishing system is installed can be effectively utilized.

According to the fire extinguishing system according to claim 3, since the mounting means is provided on the outer surface side of the accommodating means for the fire extinguishing device, for example, the worker using the fire extinguishing system can easily access the mounting means. Therefore, the work efficiency of the worker can be improved.

In this case, since the maintenance hose 32 is not attached to the supply port 453, the closing valve (not shown) of the supply port 453 is closed, so that the foam fire extinguishing agent is not discharged from the supply port 453.

(Operation-Fire extinguishing operation-End)
When ending the fire extinguishing operation, the user on the ground presses a pump stop switch (not shown) and then closes the fire hydrant valve 21 on the ground side. In this case, since the pump 42 is stopped and the space between the upstream control pipe 12 and the downstream control pipe 13 is cut off, the pressure supplied to the simultaneous release valve 23 is reduced, and the simultaneous release valve 23 is opened. The flow path of the fire extinguishing pipe 11 is closed, and the release of the foam extinguishing agent from the fire extinguishing hose 31 is stopped. After that, after draining each pipe, the fire extinguishing hose 31 is stored in the fire hydrant storage box 101. This ends the fire extinguishing operation.

(Operation-Maintenance operation-Start)
Next, when starting the maintenance operation, even if the user in the basement in FIG. 1 tries to attach the maintenance hose 32 to the supply port 453 in the state of FIG. 2, the maintenance hose 32 interferes with the operation handle 462. Since it cannot be installed, perform the following operations. Specifically, the underground user rotates the handle handle 462a of FIG. 2 clockwise to move the operation handle 462 downward (-Z direction) so that the operation handle 462 moves to the non-interference position. Move to. Then, when the operation handle 462 moves to the non-interfering position, the on-off valve 461 is in a state of closing the flow path, and the maintenance hose 32 can be attached to the supply port 453.

Next, the underground user attaches the maintenance hose 32 to the supply port 453 as shown in FIG. In this case, the closing valve (not shown) inside the supply port 453 is opened by the tip of the maintenance hose 32 inserted into the supply port 453, and the foam extinguishing agent of the fire extinguishing pipe 11 is applied to the vertical pipe 451 and the horizontal pipe. It can be supplied to the maintenance hose 32 via 452. In this way, the maintenance hose 32 can be attached to the supply port 453 only when the operation handle 462 has moved to the non-interfering position and the on-off valve 461 closes the flow path. Even though the maintenance hose 32 is attached to the 453, it is possible to prevent the on-off valve 461 from opening the flow path.

Next, the underground user opens the underground fire hydrant valve 22 after starting the pump 42 by pressing the pump start switch (not shown) in the basement. In this case, the simultaneous release valve 23 opens the flow path of the fire extinguishing pipe 11 in the same manner as described in "(Operation-Fire extinguishing operation-Start)", and the water in the water tank 41 extinguishes the fire. After being supplied to the pipe 11, it is supplied to the ejector 44 via the automatic pressure regulating valve 24, and is stirred with the foam stock solution of the foam tank 43 by the ejector 44 to become a foam extinguishing agent, and the foam extinguishing agent is supplied to the supply unit. It is supplied to 45 and the opening / closing part 46. In this case, since the on-off valve 461 of FIG. 4 closes the flow path and the closing valve (not shown) of the supply port 453 is open, the supplied foam fire extinguishing agent connects the vertical pipe 451 and the horizontal pipe 452. It is supplied to the maintenance hose 32 and released via the maintenance hose 32. Then, the underground user knows whether or not the foam fire extinguishing agent is released from the maintenance hose 32, and whether or not the fire extinguishing system 100 operates normally based on the release amount, the release time, or the like. It is possible to confirm using the method of. In this case, since the on-off valve 461 closes the flow path, it is possible to prevent the foam fire extinguishing agent from being released from the fire extinguishing hose 31.

(Operation-Maintenance operation-End)
When the maintenance operation is completed, the underground user presses the pump stop switch (not shown) and then closes the underground fire hydrant valve 22. In this case, the pump 42 is stopped and the release of the foam fire extinguishing agent from the maintenance hose 32 is stopped in the same manner as in the case described in "(Operation-Fire extinguishing operation-End)".

Next, the underground user removes the maintenance hose 32 of FIG. 4 from the supply port 453, and then rotates the handle handle 462a counterclockwise so that the operation handle 462 moves to the interference position. The operation handle 462 is moved upward (+ Z direction). Then, when the operation handle 462 moves to the interference position, the on-off valve 461 is in a state of opening the flow path, and it becomes impossible to attach the maintenance hose 32 to the supply port 453. This ends the maintenance operation.

(Effect of embodiment)
As described above, according to the present embodiment, when the on-off valve 461 opens the flow path, the attachment of the maintenance hose 32 to the supply port 453 is hindered, and the on-off valve 461 closes the flow path. By permitting the attachment of the maintenance hose 32 to the supply port 453, for example, the maintenance hose 32 can be attached to the supply port 453 only when the on-off valve 461 closes the flow path. Due to a human error (for example, forgetting to close the flow path), the on-off valve 461 opens the flow path even though the maintenance hose 32 is attached to the supply port 453. Since it is possible to prevent the occurrence of a state, it is possible to prevent the foam fire extinguishing agent from being released from the fire extinguishing hose 31 when performing maintenance due to the above human error, which is annoying to the surroundings. Maintenance can be performed reliably without applying a hose.

Further, the operation handle 462 moves to an interference position so as to hinder the attachment of the maintenance hose 32 to the supply port 453 when the on-off valve 461 opens the flow path, and the on-off valve 461 closes the flow path. By moving to a non-interfering position so as to allow the maintenance hose 32 to be attached to the supply port 453, for example, depending on whether the operation handle 462 and the maintenance hose 32 interfere with each other. Since the installation of the maintenance hose 32 to the supply port 453 can be hindered or permitted, the on-off valve 461 opens the flow path even though the maintenance hose 32 is attached to the supply port 453. It is possible to reliably prevent the occurrence of a condition.

Further, since the mounting control means is an operation handle 462 for operating the on-off valve 461, for example, the function of the mounting control means can be realized by using the parts of the conventional fire extinguishing system. It is possible to reduce the cost of parts or the cost of remodeling to realize the function, and the fire extinguishing system 100 can be provided at a low price.

[Variation example with respect to the embodiment]
Although the embodiments according to the present invention have been described above, the specific configuration and means of the present invention may be arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. Can be done. Hereinafter, such a modification will be described.

(About the problem to be solved and the effect of the invention)
First, the problem to be solved by the invention and the effect of the invention are not limited to the above-mentioned contents, and may differ depending on the implementation environment and the details of the configuration of the invention, and only a part of the above-mentioned problems. Or may produce only some of the effects described above.

(About distribution and integration)
Further, the above-described configuration is a functional concept, and does not necessarily have to be physically configured as shown in the figure. That is, the specific form of dispersion or integration of each part is not limited to the one shown in the drawing, and all or a part thereof can be functionally or physically dispersed or integrated in any unit. The term "system" in the present application is not limited to a system composed of a plurality of devices, but includes a system composed of a single device. Further, the "device" in the present application is not limited to a device composed of a single device, but includes a device composed of a plurality of devices.

(Supply and open / close parts-configuration)
Further, in the above embodiment, the case where the supply unit 45 and the opening / closing unit 46 of FIG. 2 are used has been described, but a supply unit and an opening / closing unit different from the supply unit 45 and the opening / closing unit 46 may be used. FIG. 5 is a side view illustrating a supply portion and an opening / closing portion of a modified example in a state where the maintenance hose is removed while the operation handle is moved to the interference position, and FIG. 6 is a plan view of FIG. FIG. 7 is a side view illustrating the supply unit, the opening / closing unit, and the virtually illustrated maintenance hose of the modified example in a state where the operation handle is moved to the interference position, and FIG. 8 is an operation. FIG. 9 is a side view illustrating a supply portion, an opening / closing portion, and a maintenance hose of a modified example in a state where the handle is moved to a non-interference position, and FIG. 9 is a plan view of FIG. In the following description, the Y direction shown in FIGS. 6 and 9 will be described below assuming that the directions are orthogonal to the X direction and the Z direction.

First, the supply section 55 of FIGS. 5 and 6 is modified so that the length of the vertical pipe 451 is shortened in the supply section 45 of FIG. 2, and the configuration other than the changed configuration is the same as that of the supply section 45. It is the same as the structure of the name. The supply unit 55 includes, for example, a vertical pipe 551, a horizontal pipe 552, and a supply port 553.

Further, the opening / closing section 56 of FIGS. 5 and 6 realizes the same function as the opening / closing section 46 of FIG. 2 with a configuration different from that of the opening / closing section 46. The opening / closing section 56 includes, for example, an on-off valve 561 and an operation handle 562, as shown in FIGS. 5 and 6.

The on-off valve 561 opens and closes by operating, for example, the operation handle 562. The operation handle 562 moves to an interference position described later so as to hinder the attachment of the maintenance hose 32 to the supply port 553 when the on-off valve 561 opens the flow path, and the on-off valve 561 closes the flow path. When the hose 32 is attached to the supply port 553, the hose 32 is moved to a non-interference position described later. For example, a handle handle 562a and a handle shaft 562b are provided.

Here, the "interference position" is the position of the operation handle 562, which interferes with the maintenance hose 32 in the state of being attached to the supply port 553, and is virtually illustrated in FIG. 7. At least a part of the operation handle 562 overlaps (that is, interferes with) the maintenance hose 32. For example, the handle handle 562a described later of the operation handle 562 is provided in the vicinity of the supply port 553. It is a position, and as an example, it is the position of the operation handle 562 shown in FIG. Further, the "non-interference position" is a position of the operation handle 562, which does not interfere with the maintenance hose 32 in a state of being attached to the supply port 553, and is virtually illustrated in FIG. 7. The entire operation handle 562 does not overlap (that is, does not interfere with) the maintenance hose 32. For example, the handle handle 562a described later of the operation handle 562 is located away from the supply port 553. Yes, as an example, it is the position of the operation handle 562 shown in FIG.

The handle handles 562a of FIGS. 5 and 6 are operating means operated by the user, for example, having a flat plate shape extending in a rod shape, in the directions A1 and A2 of FIG. 6 with reference to the handle shaft 562b. It is configured so that it can be rotated by 90 degrees.

The handle shaft 562b of FIGS. 5 and 6 is a support means for rotatably supporting the handle handle 562a, and transmits a force for opening and closing the on-off valve 561 by rotating the handle handle 562a. It is a means, for example, one provided in the fire extinguishing pipe 11.

Then, for example, the operation handle 562 including the handle handle 562a and the handle shaft 562b is opened and closed when the handle handle 562a is moved to a non-interfering position by rotating the handle handle 562a in the direction A1. It is known that the on-off valve 561 opens the flow path when the handle handle 562a moves to the interference position by rotating the handle handle 562a in the direction A2 while the valve 561 closes the flow path. It shall be configured using a mechanism or the like.

(Supply and open / close parts-maintenance operation)
In the fire extinguishing system of the modified example configured as described above (specifically, in the fire extinguishing system 100 of the embodiment, the supply unit 45 and the opening / closing unit 46 are replaced with the supply unit 55 and the opening / closing unit 56), the maintenance operation is performed. When the user in the basement tries to attach the maintenance hose 32 to the supply port 553 in the state of FIGS. 5 and 6, the maintenance hose 32 interferes with the operation handle 562 to attach the maintenance hose 32. Is not possible, so perform the following operations. Specifically, the underground user rotates the handle handle 562a of FIG. 6 in the direction A1 to move the handle handle 562a to a non-interfering position. Then, when the handle handle 562a moves to the non-interfering position, the on-off valve 561 is in a state of closing the flow path, and the maintenance hose 32 can be attached to the supply port 553. Next, as shown in FIGS. 8 and 9, the underground user attaches the maintenance hose 32 to the supply port 553, and then performs the same operation as described in the embodiment to start the maintenance operation. To do.

Next, when terminating the maintenance operation, the underground user performs a predetermined operation (such as pressing a pump stop switch (not shown) described in the embodiment), and then the maintenance hose shown in FIGS. 8 and 9 is performed. After removing the 32 from the supply port 553, the handle handle 562a is rotated in the direction A2 of FIG. 6 to move the handle handle 562a to the interference position. Then, when the handle handle 562a moves to the interference position, the on-off valve 561 is in a state of opening the flow path, and it becomes impossible to attach the maintenance hose 32 to the supply port 553. This ends the maintenance operation.

(About mounting control means (1))
Further, in the above embodiment, the case where the mounting control means is the operation handle 462 of FIG. 2 has been described, but the present invention is not limited to this. For example, when a protrusion is provided near the supply port 453 and the on-off valve 461 is open, the protrusion protrudes to prevent the maintenance hose 32 from being attached to the supply port 453, while the on-off valve 461 When is closed, the protrusion may be retracted to allow attachment of the maintenance hose 32 to the supply port 453.

(About mounting control means (Part 2))
Further, in the above embodiment, the case where the operation handle 462 of FIG. 2 is moved to the interference position or the non-interference position to hinder or permit the attachment of the maintenance hose 32 to the supply port 453 has been described. Not limited to this. For example, the handle handle 462a of the operation handle 462 is configured to be used as a joint of the supply port 453 and the maintenance hose 32, and the handle handle 462a is used as the handle shaft only when the on-off valve 461 is closed. It may be configured so that it can be removed from 462b, and the maintenance hose 32 cannot be attached to the supply port 453 unless the handle handle 462a as a joint is used. In this configuration, when the on-off valve 461 is open, the handle handle 462a cannot be removed from the handle shaft 462b, which hinders the attachment of the maintenance hose 32 to the supply port 453. On the other hand, when the on-off valve 461 is closed, the handle handle 462a can be removed from the handle shaft 462b and used as a joint, so that the maintenance hose 32 can be attached to the supply port 453. Become.

(About automatic control)
Further, in the above embodiment, the case where the on-off valve 461 and the operation handle 462 of FIG. 2 are manually operated has been described, but for example, these devices may be automatically controlled. For example, the on-off valve 461 is configured as a solenoid valve, the operation handle 462 is configured to be movable by an actuator, and a control computer is provided in the fire prevention system 100 of FIG. It may be configured to control the opening / closing and the movement of the operation handle 462. Specifically, as an initial state before performing the maintenance operation, when the control computer opens the on-off valve 461 and moves the operation handle 462 to the interference position and receives a maintenance request from the user, the on-off valve is opened. The operation handle 462 may be configured to be closed and the operation handle 462 to be moved to a non-interfering position.

(About alarm (1))
Further, in the above embodiment, the fire system 100 of FIG. 1 may be provided with an open / close state detection sensor, a mounting state detection sensor, and an alarm device. The open / close state detection sensor is a detection means for detecting the open / closed state of the on-off valve 461 of FIG. 2, and specifically, it detects whether the on-off valve 461 is open or closed, and is known, for example. A valve sensor or the like, or any sensor that can be realized by using a known sensor other than the valve sensor can be used. The attachment state detection sensor is a detection means for detecting the attachment state of the maintenance hose 32 to the supply port 453. Specifically, it detects whether or not the maintenance hose 32 is attached to the supply port 453. For example, a known switch sensor provided inside the supply port 453, or any sensor that can be realized by using a known sensor other than the switch sensor can be used. Further, the alarm device is an alarm means that gives an alarm based on the detection result of the open / closed state detection sensor or the detection result of the mounting state detection sensor. An alarm is issued based on the alarm, and for example, a display device such as a small liquid crystal display that displays image information, a speaker that outputs audio information, or the like can be used. The display device and the speaker can be provided at any place as long as the user can be notified of the alarm. For example, the supply unit 45 and the opening / closing unit 46 in the fire extinguishing pipe 11 of FIG. 2 can be provided. It may be provided in between.

With this configuration, a control computer may be provided for the fire system 100 of FIG. 1, and the control computer may acquire the detection results of each sensor and issue an alarm.

Specifically, the control computer has a detection result indicating that the on-off valve 461 is closed and the maintenance hose 32 is attached as the detection result of each sensor (hereinafter, "first detection result"). ), Or the detection result indicating that the on-off valve 461 is closed and the maintenance hose 32 is not attached (hereinafter referred to as the "second detection result"), or the on-off valve 461 There is a possibility of acquiring a detection result (hereinafter, referred to as "third detection result") indicating that the hose 32 is open and the maintenance hose 32 is not attached. Since the operation handle 462 of FIG. 2 functions as the attachment control means, the detection result indicating that the on-off valve 461 is open and the maintenance hose 32 is attached is not acquired.

Then, when the control computer acquires the first detection result, in order to notify the possibility that maintenance is being performed, the control computer sends an image or voice indicating that maintenance is being performed to the alarm device as an alarm. It may be output. Further, when the control computer acquires the second detection result, the control computer outputs an image or sound indicating that the on-off valve 461 is closed in order to notify the possibility that the on-off valve 461 has been forgotten to be opened after the maintenance is completed. It may be output to the alarm device as an alarm. In addition, when the control computer acquires the third detection result, the control computer uses an image or sound indicating that it is in the standby state as an alarm in order to notify that it is in the normal standby state without maintenance. It may be configured to output to an alarm device.

(About alarm (2))
Further, in the above "(Alarm (No. 1))", an LED or the like may be used as the alarm device.

In this configuration, for example, an alarm related to maintenance can be issued by issuing an alarm based on the detection result of the open / closed state of the on-off valve 461 and the attachment state of the maintenance hose 32 to the supply port 453. , The maintenance status can be notified to the worker. In particular, for example, when the on-off valve 461 is closed and the maintenance hose 32 is not attached to the supply port 453, there is a possibility that the on-off valve 461 has been forgotten to be opened even though the maintenance has been completed. It is possible to notify that there is something, and it is possible to prevent human error related to maintenance.

(About supply control (1))
Further, in the above embodiment, the fire system 100 of FIG. 1 may be provided with a maintenance storage box and a supply control valve. The maintenance storage box is a storage means for accommodating the maintenance hose 32, and specifically, a hollow portion for accommodating the maintenance hose 32 when maintenance is not performed is provided. For example, it is provided in the vicinity of the floor slab storage box 102, and is provided with a storage detection sensor for detecting whether or not the maintenance hose 32 is housed. Further, the supply control valve is the downstream side of the simultaneous release valve 23 in the fire extinguishing pipe 11 when the underground fire hydrant valve 22 is operated by the user when the maintenance hose 32 is not accommodated by the maintenance storage box. When the maintenance hose 32 is housed in the maintenance storage box, when the underground fire hydrant valve 22 is operated by the user, it is downstream of the simultaneous release valve 23 in the fire extinguishing pipe 11. It is a supply control means that makes it impossible to start the supply of water to the side. For example, an electromagnetic valve provided in series with the underground fire hydrant valve 22 between the upstream side control pipe 12 and the downstream side control pipe 13. Can be configured as.

With this configuration, a control computer may be provided for the fire system 100 of FIG. 1, and the control computer may acquire the detection result of the accommodation detection sensor and control the supply control valve.

Specifically, the control computer closes the supply control valve when it obtains a detection result indicating that the maintenance hose 32 is accommodated as a detection result of the accommodation detection sensor. In this case, even if the underground fire hydrant valve 22 is opened after the pump 42 is started, the supply control valve provided in series with the underground fire hydrant valve 22 closes the flow path, so that the pressure is applied to the simultaneous release valve 23. Since the simultaneous release valve 23 remains closed, it becomes impossible to start supplying water to the downstream side of the simultaneous release valve 23 in the fire extinguishing pipe 11.

On the other hand, when the control computer obtains the detection result indicating that the maintenance hose 32 is not accommodated as the detection result of the accommodation detection sensor, the control computer opens the supply control valve. In this case, when the underground fire hydrant valve 22 is opened after the pump 42 is started, the supply control valve provided in series with the underground fire hydrant valve 22 opens the flow path, so that the pressure is applied to the simultaneous release valve 23. Since the simultaneous release valve 23 is supplied and opened, it is possible to start supplying water to the downstream side of the simultaneous release valve 23 in the fire extinguishing pipe 11.

In this configuration, when the maintenance hose 32 is not housed in the maintenance storage box and the underground fire hydrant valve 22 is operated by the user, it goes to the downstream side of the simultaneous release valve 23 in the fire extinguishing pipe 11. When the maintenance hose 32 is housed in the maintenance storage box and the underground fire hydrant valve 22 is operated by the user, the downstream of the simultaneous release valve 23 in the fire extinguishing pipe 11 By making it impossible to start supplying water to the side, for example, preparations for using the maintenance hose 32 for performing maintenance (for example, taking out the maintenance hose 32 from the maintenance storage box and attaching it to the supply port 453) can be performed. Since it is possible to prevent the supply of water to the downstream side of the simultaneous release valve 23 in the fire extinguishing pipe 11 from being started even though it has not been completed, it is appropriate that the maintenance hose 32 is ready for use. In this case, the supply of water to the downstream side of the simultaneous release valve 23 in the fire extinguishing pipe 11 can be started, and appropriate maintenance can be performed.

(About supply control (2))
Further, regarding the above "(About supply control (No. 1))", a pump starting device is provided together with the supply control valve or instead of the supply control valve, and the pump starting device acquires the detection result of the accommodation detection sensor. And, the start of the pump 42 may be controlled after being configured to receive a start signal from the pump start switch (not shown) for starting the pump 42 of FIG. 1 described above. Specifically, the pump starter does not start the pump 42 when it receives a start signal from the pump start switch and obtains a detection result indicating that the maintenance hose 32 is accommodated. The pump 42 may be started when a detection result indicating that the maintenance hose 32 is not accommodated is obtained. In this case, the pump starting device corresponds to the "supply control means" and the pump starting switch corresponds to the "operating means".

(About the accommodation means for fire extinguishing devices)
Further, in the above embodiment, the case where the above-mentioned underground side storage device group is housed in the storage box 102 under the block copy of FIG. 1 has been described, but the present invention is not limited to this. For example, all or a part of the underground side accommodation device group may be accommodated in the fire extinguishing device accommodation means. Here, the "fire extinguishing device accommodating means" is a fire extinguishing device accommodating means for accommodating the fire extinguishing device, and specifically, at least a part of the fire extinguishing device accommodating means is only a frame frame surrounding the fire extinguishing device. It is composed of. Further, the "fire extinguishing device" is a device for outputting the fire extinguishing liquid, for example, a device or a component for supplying the fire extinguishing liquid to the fire extinguishing hose 31, and is used in the underground side accommodating device group. It is a concept including the included devices or components. FIG. 10 is a perspective view of the fire extinguishing device accommodating portion, and FIG. 11 is a front view of the fire extinguishing device accommodating portion in a state where the underground side accommodating device group is accommodated. The fire extinguishing device accommodating portion 600 actually accommodates the entire group of underground accommodating devices, but in FIG. 11, for convenience of explanation, the underground fire hydrant valve 22, the automatic pressure regulating valve 24, and foam are accommodated. The tank 43 and the ejector 44 are shown in a rectangular shape for convenience of explanation. A system including a "fire extinguishing device accommodating unit 600" and an "underground side accommodating device group" corresponds to a "fire extinguishing system".

For example, the + Z1 direction is referred to as the upper side, and- The Z1 direction is referred to as the lower side, the X1 direction is referred to as the left-right direction, for example, the + X1 direction is referred to as the right side, the -X1 direction is referred to as the left side, and the Y1 direction is referred to as the front-back direction, for example, the + Y1 direction. The front side will be referred to, and the −Y1 direction will be referred to as the back side (note that the same applies to the XX direction in FIG. 11).

The fire extinguishing device accommodating unit 600 shown in FIGS. 10 and 11 is a fire extinguishing device accommodating means for accommodating the underground side accommodating device group, and is different from the fire hydrant storage box 101 of FIG. 1, for example. It is provided on the underground side where an evacuation passage or the like below the floor slab 900 in FIG. 1 is laid. The specific type and configuration of the fire extinguishing device accommodating portion 600 is arbitrary, but for example, at least a part thereof is composed of only a frame frame surrounding the underground side accommodating device group, and is omitted as a whole. It is made of metal and has a rectangular parallelepiped shape. As an example, as shown in FIG. 10, the bottom plate 61, the lower frame 62, the vertical frame 63, the middle frame 64, the upper frame 65, and the back plate 66, And a hanging upper portion 67 is provided. In reality, the fire extinguishing device accommodating unit 600 also includes an attachment mechanism that is a mechanism for attaching and fixing the underground side accommodating device group to the fire extinguishing device accommodating unit 600 itself. Since a known mechanism for attaching or fixing various devices can be applied, the description thereof will be omitted here.

The bottom plate 61 is a member for forming the bottom of the fire extinguishing device accommodating portion 600, and has a substantially rectangular shape, for example.

Further, the lower frame 62 is a frame frame on the lower side (-Z1 direction) of the fire extinguishing device accommodating portion 600, and is, for example, a known joining method (for example, integral formation, screwing, or welding) on the four sides of the bottom plate 61. Etc.). The vertical frame 63 is a frame frame that is erected in the vertical direction (Z1 direction) in the fire extinguishing device accommodating portion 600. For example, the four corners of the bottom plate 61 in the lower frame 62 that is connected to the bottom plate 61. It is bound to the portion corresponding to by the above-mentioned known binding method. The middle frame 64 is provided at a position slightly above (+ Z1 direction) from the middle point between the lower frame 62 and the upper frame 65 of the fire extinguishing device accommodating portion 600 in the vertical direction (Z1 direction). This is a frame frame, for example, which is bonded to the vertical frame 63 by the above-mentioned known bonding method. Further, the upper frame 65 is a frame frame on the upper side (+ Z1 direction) of the fire extinguishing device accommodating portion 600, and is, for example, bonded to the vertical frame 63 by the above-mentioned known bonding method.

Further, the back plate 66 is an attachment means for attaching predetermined electrical equipment (for example, a terminal block for exchanging electric signals such as a disaster prevention panel and a fire hydrant, a telephone jack, or any equipment such as a pump start switch). Is. The type and specific configuration of the back plate 66 are arbitrary, but for example, the back plate 66 is provided on the outer surface side of the fire extinguishing device accommodating portion 600, and as an example, the back side of the fire extinguishing device accommodating portion 600 is provided. It is provided on the upper side (+ Z1) of (-Y1) and closes a part of the opening provided on the upper side (+ Z1) of the back side (-Y1) of the fire extinguishing device accommodating portion 600. It has a substantially rectangular shape, and is coupled to the upper side (+ Z1) of the back surface side (−Y1) of the fire extinguishing device accommodating portion 600 by the above-mentioned known coupling method.

Further, the hanging upper portion 67 is a lifting means for lifting and moving the fire extinguishing device accommodating portion 600 itself.
